Making of a Demand-driven Acquisition Model Highly specialised researchers / Students in the know Need immediate access to the most and recent and relevant information available Searching for practical solution for speedy, cost-effective delivery of content

History Demand-driven Acquisition Some early milestones… June 2006 – Swinburne University of Technology & Brown University were first libraries to load MARC records into OPAC for EBL’s entire catalogue April 2006 – CERN first library to implement automated MARC ‘feed’ to OPAC based on profile April 2005 – Curtin University first utilises mediated demand-driven acquisition Approximately 60% of all libraries now use some form of demand-driven acquisition.

EBL’s Demand-driven Acquisition Explained Demand-driven access harnesses of the immediacy of the digital medium to provide a just-in-time delivery solution… Demand-driven Acquisition enables libraries to make ebooks visible to patrons without purchasing the titles outright. Titles can then be ‘rented’, requested or purchased according to pre-defined set by the library. –Access to non-owned either through library OPAC (by loading MARC records) and/or within the EBL platform –Limited free browsing for non-owned titles –Beyond the browse period, libraries decide what permissions apply

Options for Discovery Libraries decide which titles will be available… All titles in EBL catalogue Pre-selected titles Based on Profile – (Built in ‘approval plan’) – MARC updates and visibility based on profile De-duplication – Identify and suppress titles owned by library through other source Libraries determine how titles will be discovered: Loading MARC records in catalogue Discovery within the EBL portal Through federated search tools

These are averages from accounts using non-mediated demand-driven acquisition for a 12 month period – July 07 –June 08 > Ratio Browse to short-term loan (STL) 50.5% of non-owned titles browsed triggered a short-term loan > Ratio Browse to Auto-purchase 4.6% of browsing of non-owned titles triggered an auto-purchase (purchased after designated # of short-term loans) > Ratio STL to Auto-purchase 9.1% of STLs turn into auto-purchase > Average price STL $11.50 (12% list price) / Average auto-purchase price = $92.20 Notes: We assume that the auto-purchase rate goes up the longer a library uses the demand-driven model The browse to STL and browse to auto-purchase ratio will be slightly skewed due to the fact that STLs and auto-purchases can be triggered directly by a download (i.e. skipping the browse stage). The auto-purchase point (i.e. purchase after x STLs) varies from library to library. These stats show an average. Stats on Automated DDA users 2007/2008

Benefits of Demand-driven Acquisition Some of the benefits of demand-driven access… Provides critical mass of widest selection of titles available to patrons Justification of Spending - Budget goes toward funding what actually gets used Budget can be stretched to provide access to a greater number of titles Eliminates time required for selectors to search for titles and purchase Patrons have more immediate access most up to date content EBL profiling tools create a build-in ‘approval plan’ Seamless access/workflow for libraries and patrons Titles purchased based on demand have higher use once purchased Provides alternative to ILL Publishers/Authors = greater exposure of works to end users
